Medifast Diet Summary: How Does It Work?

Medifast dieters eat 6 small meals a day, 5 of which are Medifast products like shakes, bars, and soup. The 6th meal can be eaten anytime, and consists of a “lean and green” entree consisting of a protein (healthy fish, chicken, or other meat or vegetable protein).

As you can imagine, this often results in fast weight loss, as you are drastically reducing the number of calories that you consume.  Medifast costs about $300 per month (similar to Nutrisystem) in their packaged meals, plus the cost of your one other meal each day.

Once you reach your ideal weight, you transition into a maintenance phase which establishes your ideal caloric intake, and weans you off of their meals.

  • Positives: Medifast ranks highly as a fast weight-loss diet, (2-5 pounds a week) and it’s relatively easy, as there are no points to calculate or counting calories or carbs. Positive reviews mention seeing fast results
  • Negatives: The downside of the fast weight loss is that it is low-calorie with limited menu options from their product line, and small portions. About half of dieters drop out before the first year is over. Eating out can be challenging, and drinking alcohol is not encouraged, as it is high in calories and can make you hungry.

For that reason, we’ve highlighted the best ratings and reviews of the Medifast diet for you to consider, but first, here’s a quick overview.

thumbs down

Sometimes the negative reviews for a diet or weight loss program are the most interesting and helpful. Why did it fail? Why do half the people on the diet quit?

One option might seem like the perfect weight loss program on paper, but everyone is different. Also, be sure to compare Medifast against other popular diets like Weight Watchers & the Nutrisystem diet. If you specifically want to find negative reviews, check out sites like
